Creatures can spawn with differently colored stars, if you want to. Each color tweaks the creature in a different way:

Magenta - Quick - Moves faster, 40% increased movement speed

Red - Aggressive - Attacks faster and tries to hit you more often, Attack speed increased by 25%, interval between two attack waves and circle time reduced by 50%, interval between circles increased by 150%

Green - Regenerating - Regenerates health over time, BaseHeal = Health at 0 stars * (1 + 0.25 * stars), Healing = BaseHeal * (10 * log(max(10, BaseHeal - 1000)) / (BaseHeal + 1000)) * 1.2 / second

Cyan - Curious - Comes checking for you from a farther distance, Hear and view range increased by 100%

White - Splitting - Splits in two lower level enemies with the same color upon death, Example: A 4 star Greydwarf will split into two 2 star Greydwarfs on death
